Welcome to the forum. Good to have you with us!
I'm a bit of a clean freak myself (although since my son was born the balance went more towards freak while clean took a backseat). I was a little bit concerned when Clouds came to live with us, as there was no way I was going to have a bird stuck in a cage for the rest of his life. I knew he would have to come out and therefore poop question popped...
Anyway, long story short: I do occasionally find tiny little droppings under the places where he's been perching but nearly not as much as I had anticipated. True, at the moment he's still very new and therefore only perches in a handful of favourite spots. The fact that we have bird-friendly places for him helps tremendously (a tree made out of a branch and an old parasol stand, a little play gym and of course his cage).
There are a few sports that he's tried in the past but got gently shooed away from consistently and now doesn't even approach (or won't stay on without us having to do anything about it anymore). Sofas are a big no-no for example.
I am still curious to see how things will evolve as he becomes more adventurous, so the answers that you're going to get from our much more experienced members will be interesting to me too
I look forward to reading more of your posts (we also love pictures!)
